  • Laboratory Leaching Test Procedure 911metallurgist

    Laboratory Leaching tests of mine wastes are typically performed using procedures that fall into two basic categories batch and continuous. These categories are analogous to batch and continuous reactor methods used in metallurgical processing. Batch reactors for leaching tests can be in the form of a closed vessel, a cell, or a column.
